World's Most Endangered Tribe Being Slaughtered For Logging

'They're killing us': world's most endangered tribe cries for help. Logging companies keen to exploit Brazil's rainforest have been accused by human rights organisations of using gunmen to wipe out the Awá, a tribe of just 355. Survival International, with backing from Colin Firth, is campaigning to stop what a judge referred to as 'genocide'.

Trundling along the dirt roads of the Amazon, the giant logging lorry dwarfed the vehicle of the investigators following it. The trunks of nine huge trees were piled high on the back – incontrovertible proof of the continuing destruction of the world's greatest rainforest and its most endangered tribe, the Awá.

Yet as they travelled through the jungle early this year, the small team from Funai – Brazil's National Indian Foundation – did not dare try to stop the loggers; the vehicle was too large and the loggers were almost certainly armed. All they could do was video the lorry and add the film to the growing mountain of evidence showing how the Awá – with only 355 surviving members, more than 100 of whom have had no contact with the outside world – are teetering on the edge of extinction.

It is a scene played out throughout the Amazon as the authorities struggle to tackle the powerful illegal logging industry. But it is not just the loss of the trees that has created a situation so serious that it led a Brazilian judge, José Carlos do Vale Madeira, to describe it as "a real genocide". People are pouring on to the Awá's land, building illegal settlements, running cattle ranches. Hired gunmen – known as pistoleros – are reported to be hunting Awá who have stood in the way of land-grabbers. Members of the tribe describe seeing their families wiped out. Human rights campaigners say the tribe has reached a tipping point and only immediate action by the Brazilian government to prevent logging can save the tribe.

This week Survival International will launch a new campaign to highlight the plight of the Awá, backed by Oscar-winning actor Colin Firth. In a video to be launched on Wednesday, Firth will ask the Brazilian government to take urgent action to protect the tribe
